Close the magnet and screw it.
Do NOT secure the screw yet, leave the magnet
loose enough to be adjusted until the speed sensor
is fixed. Continue to fix the speed sensor.
Place the speed sensor on the inner side of a chain
stay. Make sure the speed sensor and the magnet
should pass facing each other with no more than
25 millimeters between the two.
Thread and wind the included two cable ties (thicker ones) to secure the speed sensor onto the chain
stay. Trim the cable ties if they hinder the rotation
Secure the speed sensor to make sure it is firmly attached to the spoke without moving upward or
downward while cycling.
